Question regarding motor noises:

Question regarding motor noises: This is a stock CR-10 except for the fan shroud and a few other knobs. I’ve got the printer dialed decently and am considering noise reduction. Based on the video’s noises do you think the Trinamic stepper motor drivers would help? I watched Tom’s video and think it might be. Am I on the right track?

Yep, that’s stepper song from the step pulses being taken by the motors. You have a few options:

  1. Trinamic drivers with a quiet running mode
  2. Install engineered stepper dampers such as https://www.ultibots.com/nema-17-damper-astrosyn-my17rmdamp/
  3. Switch to a 32bit controller that can handle high step pulse rates without double/quad pulsing, and raise the microstep level to 1/32 or higher (note Marlin/Melzi will still be loud on fast moves even if you increase the microstepping)
  4. Put the whole thing in a box

The Trinamics are basically silent in StealthChop mode but there are some potential issues with loss of position during aggressive motions. The Trinamic microstep interpolation mode Microplyer doesn’t lose any torque and will give significantly less noise.

Dampers cut noise about 70%. Each time you cut the microstep size in half, it cuts the noise in half too. A simple enclosure is worth maybe 30% quieter. depending on what you build it out of. Personally, I use dampers and higher microstepping with 32 bit controllers when possible. Lots of people like StealthChop though.

Yes they will.

yes
And you might want to add some Nema 17 dampers as well. (google it=)

@Ryan_Carlyle Thanks… I had to restore your comment because it got flagged as SPAM for some reason. I appreciate the help.

@Johan_Jakobsson Thanks, I forgot about those and think I’ll try those first since they are a much lower learning curve.

Here’s the final result after 27.5 hours. I still need to do some more cleanup of the support areas but overall I’m pretty happy.
